What xsser_scan does on Hexstrike Ai
AI agents invoke xsser_scan to trigger actions in Hexstrike Ai. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why xsser_scan is rated High
This tool actively executes XSSer, an automated XSS attack/testing framework, against targets. It runs external offensive security tooling that probes and tests web applications for cross-site scripting vulnerabilities. The effects depend on the target arguments provided and can include sending malicious payloads to live systems.

The rule that runs xsser_scan safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hexstrike Ai, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For xsser_scan, this is the rule to start with:
xsser_scan stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hexstrike Ai, apply this rule, and every xsser_scan call is checked against it from then on.
Questions about xsser_scan
Execute XSSer for XSS vulnerability testing with enhanced logging. It is categorised as a Execute tool in the Hexstrike Ai MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Hexstrike Ai MCP server in PolicyLayer and add a rule for xsser_scan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hexstrike Ai. Nothing to install.
xsser_scan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the xsser_scan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for xsser_scan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
xsser_scan is provided by the Hexstrike Ai MCP server (0x4m4/hexstrike-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
